ICD-10-CM G06.0
CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

G06.0 is a billable ICD-10-CM diagnosis code for intracranial abscess and granuloma. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 23 through 24, 94 through 96, 791, 793. As a secondary diagnosis, it counts as a major complication or comorbidity (MCC) and places an inpatient stay in the highest severity level of its MS-DRG family. It does not count, however, when the principal diagnosis is one of 75 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under CNS abscess.

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to G06.0: its own notes plus those printed at G06 and Chapter 6. A note printed at a category, block or chapter applies to every code under it.

Applicable To

Conditions this code is used for: synonyms of the title or, for "other specified" codes, the conditions assigned to it. The list is not exhaustive.

  • Brain [any part] abscess (embolic)
  • Cerebellar abscess (embolic)
  • Cerebral abscess (embolic)
  • Intracranial epidural abscess or granuloma
  • Intracranial extradural abscess or granuloma

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

  • tuberculous intracranial abscess and granuloma (A17.81)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Chapter 6 (G00-G99) Diseases of the nervous system applies to 700 codes
  • certain conditions originating in the perinatal period (P04-P96)
  • certain infectious and parasitic diseases (A00-B99)

Patient EducationClinical

Abscess

An abscess is a pocket of pus. You can get an abscess almost anywhere in your body. When an area of your body becomes infected, your body's immune system tries to fight the infection. White blood cells go to the infected area, collect within the damaged tissue, and cause inflammation. During this process, pus forms.

Questions About G06.0Overview

What is the ICD-10 code for intracranial abscess and granuloma?

The ICD-10-CM code for intracranial abscess and granuloma is G06.0 (sometimes written as G060). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is G06.0 (Intracranial and intraspinal abscess and granuloma) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report intracranial abscess and granuloma on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does G06.0 group to?

When intracranial abscess and granuloma is the principal diagnosis on an inpatient stay, it groups to MS-DRG 793, 791, 24, 23, 96, 95, 94, with relative weights from 2.3173 to 5.7422 depending on complications. Higher weights mean higher Medicare reimbursement.

Is G06.0 a CC or MCC?

CMS lists G06.0 as an MCC (major complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it places the inpatient stay in the highest-weighted DRG of its severity family. It does not count when the principal diagnosis is one of the 75 closely related codes in its exclusion list.

Can G06.0 be reported with A17.81?

Not as a rule. The Excludes1 note on G06.0 lists "tuberculous intracranial abscess and granuloma (A17.81)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
